RFID technology company eAgile is marketing a solution known as eSeal that aims to enable the automatic tracking of containers of medication from the point of manufacture to the drugstore counter or a patient's hospital bedside. The eSeal is an ultrahigh-frequency (UHF) RFID-enabled cap that can be attached to a bottle of prescription or over-the-counter medication, and would then be tracked throughout the supply chain via eAgile's software.

EAgile, based in Grand Rapids, Mich., offers a variety of RFID-based solutions. The company began looking into new markets in recent years, and zeroed in on pharmaceuticals and health care. "We were looking at where RFID could provide more value and service to society," says Gary Burns, eAgile's CEO. Medical errors lead to illness and death at a rate of 400,000 times annually, according to Burns, and many of those are the result of patients taking the wrong medications or taking drugs at the wrong dose. In addition, counterfeit products make their way into the supply chain, which can also impact patient health.

The eSeal cap contains an integrated passive RFID inlay.

So by the third quarter of 2015, eAgile was beta-testing the eSeal, as well as its related hardware infrastructure and management software. The long-term goal, Burns says, is for the system to track every bottle from factory to consumer, though it had been initially tested by an unnamed nutraceutical company at its manufacturing facilities so that the firm could identify when its medications were bottled and shipped. That nutraceutical company has completed the beta-testing and is now ordering the caps in the millions, he reports, and plans to extend the system's use into distribution centers as well.

The eSeal solution integrates a uniquely encoded RFID inlay between a pharmaceutical bottle's closure and seal, with eAgile providing a complete cap and seal compatible with a drug manufacturer's existing production equipment. The eSeal caps and closures are made with the exact diameter of existing caps and closures that drug makers currently use to seal medicine-filled bottles. "There's already great uniformity in the nature of enclosures," Burns states.

Currently, the eSeal cap is made with an Impinj passive UHF RFID chip. The chip and inlay are located between the cap's closure and seal. The chip stores a unique identifier that can be linked to the product's name, strength, serial number and batch number, as well as to the date and location of manufacture. A version of the eSeal cap is available whereby if a cap's seal has been broken, its chip will cease to function, thereby serving to alert a manufacture that someone may have tampered with that bottle.

Once an eSeal cap is attached to a container filled with medication, its RFID tag can be interrogated by multiple makes and models of readers, installed by eAgile. In this way, the system confirms the product's serial number and links that information to the batch data in the eAgile software, which forwards that data to the user's own management software.

During the beta trial, the eSeal caps were read in this manner, following bottling, and again at the point at which cartons of product were palletized and shrink-wrapped, thus creating a record of what was being shipped, as well as when this occurred. If the tag IDs read at that time did not match the ordered products, software could display an alert to correct a problem before the shipment was delivered to a customer.

Your article is great, but it makes no mention of the Drug Supply Chain Security Act of 2014 (DSCSA), which requires end-to-end supply chain tracking for pharmaceutical supply chains in the U.S. The law will be implemented over the next eight years, and eAgile (and other RFID vendors) should definitely be eyeing the market to figure out how they can succeed.
